A sex move.
Prior to engaging in sexual acts, shoot some colored food dye down your penile shaft, through its eye. Have your bitch slob on your knob. When you are about to cum, scream out "Taste the Rainbow!" Then jizz all over her face. Your semen will be colored, and proceed to paint on your model using your tool as a paintbrush.

Also known as a Picasso.

Yo Lamarcus.
What?
You know Latoya?
Jeah.
She wanted a makeover, I'm all "Hell no!" So I Picassoed her ass.
Oh shit!
